Ana Becoach, or Ana Becoaj, is a Kabbalistic prayer invoking the power of the Divine Name. The prayer is seven lines of six words each, the first letter of each word spelling the 42 letter name of the Almighty. Written in the second century by the Kabbalist Rabbi Nehonia. It is traditionally sung before Lecha Dodi during Kabbalat Shabbat.
The phrase “untie the knot” may refer to exile in both its physical and spiritual sense. As we enter Shabbat we hope to begin experiencing its expansiveness. The plea reflects the mystical view that the forces of judgment, constriction, and negativity should not have power or authority on Shabbat. ( Siddur Lev Shalem, p. 22)
